Introduction: According to studies recently published by Vilgalys et al. (1993), Pleurotus
pulmonarius is virtually indistinguishable from P ostreatus, and differs largely in its habitat preference
for conifer woods. In the Western United States, P pulmonarius is usually found at higher
altitudes than P ostreatus which prefers the lowland, river valleys. P pulmonarius and P ostreatus
grow on a variety of hardwoods, with P pulmonarius primarily a spring mushroom and P ostreatus
growing most prevalently in the summer to fall. The North American collections, show a wider
range in color than the European collections. P pulmonarius hosts a large complex of varieties,
offering cultivators a rich resource for new strains. Most of these strains fruit in culture.

The Phoenix Mushroom
Dhingri (in northern India)
"Pleurotus sajor-caju" (mis-applied by cultivators)
Taxonomic Synonyms & Considerations: This mushroom was first published as Agaricus

features. P. pulmonarius and P. populinus both share a preference for aspen and black poplar. P
